Didn't know EAI went with the Italians, so that's 4 options, of which 3 are worth having.
Beware of lock ring salesmen though - just looked on Ben's Cycles and they claim that Mavic lock rings fit Campag. They don't, Mavic are French and 33.0mm x 1mm pitch. Condor are just as bad - when I bought my Ellipses, they told me a Shimano lock ring would work, and having proven that it wouldn't fit at all they tried to sell me a Miche which rattled around like some bizarre musical instrument.
